Not much of an opinion on modules 1 and 2.
For module 3 they seemed to go quite heavy on semiconductors and charged particles in magnetic fields last year... So prob due for something nasty on photoelectric effect/quantised radiation. Most people tend to like superconductors and theres only so...

Ok thanks... point taken. I agree the superconducting question is probably a bit ambiguous. I will update Q20.
I have also updated Q8 to make the answer more clear.
Thanks for your feedback. Much appreciated.
Q8:
I think my answer is correct.
You need to use the angle to find out the length of the wire which is in the magnetic field.
This is similar to Q7 in 2006 HSC exam which caught a lot of people out.
Q12:
I have changed the wording of the question to “least likely” to eliminate this...
Hi all,
I have put up another 20 question physics exam (there are now 4 in total).
I will put up feedback for Exam 3 tomorrow.
The highest score is 15 so far.... Give it a go if you haven't already.
Not long now... Goodluck!

I wouldn't be surprised to see a 6/7 mark question on a tricky galvanic cell of some sort.
There were large short answer questions on galvanic cells in 2009 and 2011, but they were lightly tested in 2010 and 2012...

Cheers for the feedback... much appreciated. Let me know what you think of the exam and any additions/improvements you think could be made.

Hi hjed,
Sorry only just saw this... thanks for letting me know on Q4, will take a look at the back end and see if I can find the issue.

There is less difference between lower ranked schools.
For example:
A School ranked 150 will have approx 10% of units taken get a band 6.
For a school ranked 200, around 8% of units taken will get a band 6.
However, for james ruse (rank 1)- 69% of units taken will get a band 6.
For the...
Assuming your school ranks 90 I get around 82 ATAR.
Maths and ancient the subjects that will lift your ATAR the most (all else equal).
Goodluck tomorrow
